BRUSH.-

Application ined July 17, 192'2. serial No. 575,620.

To all whom t may concern:

Be it known that I, SIMON L. ArA'roW, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented new and useful Improvements in Brushes, of which the following is a full. clear, and exact description.

This invention relates to cleaning brushes and was primarily designed for use as a container cleaner.

The general object of this invention is the provision of a cheap, simple and eicient cleaning brush for containers provided with brush sections, one of which engages the bottom of the container and the other being flexible and provided with means whereby it may be made to conform with the contour of the container wall.

This object is accomplished by providing a flexible brush section, and a rigid brush section attached to the liexible brush section and extending at right angles thereto, mountingon the flexible brush Section a handle, and positioning between the handle and the brush section spring means by which the flexible brush section may be forced to conform to the contour of different surfaces. f

This and other objects of the invention will be more clearly understood from the following detailed description and accompanying drawings,

Figure 1 is a side elevation of a brush showing it pressed into engagement with the curved wall of a container;

Figure 2 is a side elevation of the brush, showing it pressed into engagement with a container wall which is straight;

Figure 3 is a section on the line 3-3, Figure 1.

Referring to the above-mentioned drawings, the invention includes a brush section 10 having a flexible back and a rigid brush section 11 carried by the brush section 10 and extending at approximately right angles thereto. Mounted on the back of the brush section 10 are two threaded bolts 12 and 13. A plate 14 provided with a handle 15 has openings formed therein for receiving the bolts 12 and 13. This plate 14 is approximately equal in length to the brush section 10 and is retained in position on the bolts 12 and 13 by wing nuts 16 and 17. Two keepers 18 and 19 are mounted on the lower face of the plate 14 for carrying a tion of an adjustable container c leaningv tool.

The operation of this brush is as follows:

When it is desired to clean a container such as 21 shown in Figure 1, the brush is placed in the container with'the rigid section 11 lying on the bottom. Pressure is then applied to the handle, forcing the spring 20 against the flexible brush section, curving the same to conform with the shape of the container wall. Then by either rotating the container or forcin the brush around the container the container may be cleaned. The position of the plate with respect to the flexible section of the brush may be adjusted by means of the wing nut 16. In some cases, the flexible brush section 10 might be made curved. 'When such a brush is used for cleaning a straight walled container it would be engaged by the plate 14 and the spring 20, both serving to force the flexible brush section into engagement with the straight wall.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention I do not limit myself strictly to the exact details herein illustrated since manifestly the same can be Vconsiderably varied without departing from the spirit of the invention as defined in the appended claims.

Claims.

1. A cleaning tool, comprising a brush having a flexible back, a brush having a rigid back attached to the brush having a flexible back and extending at an angle thereto, a handle removably mounted on the flexible back, and a spring member positioned between the fiexible brush back and the handle for forcing the brush into engagement with surfaces having different contours.

2. A container cleaner, comprising a brush having a flexible back, a second brush member having a rigid back attached to the brush having a flexible back and extending at an'angle thereto', a handle mounted on the flexible brush back so that it may be moved relative thereto, and a spring interposed between the brush and handle being slidably attached to the latter, said spring serving to force the brush having the exible back into engagement with surfaces of different shape.

3. A. container cleaning tool, comprising a brushVY having a flexible back, and a handle 5 having a curved spring slidably mounted 0n its lower face, said handle being removably mounted on said flexible back with the spring located between the handle and said exible back, said spring serving to force the brush provided with a flexible back into 10 engagement with surfaces having'different contours.
